KUBOTA ENGINE: (See Kubota engine manual)

CAUTION: Do not use ether or starting fluid. Severe non-warrantable

engine damage will occur.

FUEL: Diesel fuel must not be mixed with gasoline, kerosene, or alcohol.

*Above 32 Degrees. #2D should be used.

*Below 32 Degrees. either #1D or a mix of #1D and #2D

may be used.

ENGINE OIL: Use only CC/CD/CE rating API index oil in your diesel

engine.

*CF is the highest rating and is highly recommended.

*Change the engine oil type according to the ambient

temperature.

above 77 F. (25 C.) SAE30 or SAE10W30

below 32 F. (0 C.) SAE10 or SAE10W30

SAE10W40

COLD WEATHER START: When the ambient temperature is below 50 F

(10 C), pre-heating is needed. The Kubota engine is equipped with quick

glow plugs. Automatic preheating is made for about 6 to 10 seconds

when starter switch key is turned to preheating position.

Start: Your unit is equipped with an (externally switched) Syncro-Start

Solenoid (Model 1753ES/1751ES).

Caution: Multiple start attempts and excessive engine cranking

could cause damage to the solenoid. Therefore, it is our

recommendation that engine cranking (pull-in coil energized) be

limited to three (3) 30 second attempts with a cool down period

120 seconds (two minutes) between each cranking attempt. After

three (3) cranking attempts, the solenoid must be allowed to cool

down to ambient temperatures before making further cranking

attempts.

Introduction

Your PIGGY BACK Delivery System was bought knowing it will give long

and useful service. To get the value built into it a small amount of time

and expense is needed to learn safe, productive operation, and to do

regular inspections and service.

This manual will tell you how to safely operate, inspect, and maintain

your PIGGY BACK forklift. Keep it with the forklift as a ready reference.

As with the use of all heavy machinery, failure to carefully follow these

instructions and use common sense may result in serious injury.

If you have questions about operating, maintaining, or obtaining parts for

your forklift; contact your Princeton dealer. They are always glad to help.

ENGINE OIL: Lube oils are differentiated according to their effi-

ciency and quality grade. Commonly used are the API

Specifications.

Approved Oils:

Non-turbocharged Engines API-Specific

CC/SE CC/SF

CD/SE CD/SF

VISCOSITY: Because the viscosity of the lube oil is greatly influ-

enced by the temperature, the choice of SAE-grade should be

governed by the ambient temperature at the engine site. Optimum

operating behavior will be attained if you use the chart below.

COLD WEATHER START: The Deutz engine is equipped with a

cold weather starting aid called “Glow Plugs”. When the tempera-

ture is below 40 F, you should use the pre-heat option. To pre-heat

the engine, turn the key to the “on” position until the pre-heat light

goes out. Then turn the key to the “start” position “the right”. If the

engine does not start, wait 1 minute before pre-heating the engine

again.

IMPORTANT: DO NOT OVERCRANK THE ENGINE

To Forklift Owners

ASME B56.1 and B56.6 are the standards for forklift operation,

rules and safety, maintenance, safe operation, training and super-

vision. You should read this manual and make it available to your

operators and their supervisors. You can get it from the American

Society of Mechanical Engineers, 345 East 47th Street, United

Engineering Center, New York, NY 10017.

ASME B56.1 and B56.6 are a key part of forklift safety. However,

making forklift operation safe involves other areas and responsibili-

ties. The forklift owner is responsible to ensure their operators

have adequate training in operating the forklift. This training

includes, but should not be limited to, classroom and hands-on

training. Forklift safety involves the forklift itself, the environment it

works in, and the people who come in contact with it. Consider

your entire operation when addressing forklift safety.

The operator’s manual is not a training manual. It is a guide to

help trained and authorized operators safely operate their forklift

by showing the proper procedures. This manual combined with

adequate operator training will help reduce situations that may

cause an accident.

Operators must be trained and qualified to operate a forklift before

actually operating one.

Forklift training and operator awareness of the forklift work area

will help ensure a safe workplace for all your employees.

To Forklift Operators

Operators must become familiar with all forklift controls, proce-

dures, and work areas. Understand what this forklift can do and its

limits. Understand and practice all safety rules.

Before driving a forklift, the user must inspect it completely to

insure safe operation. This is a requirement of OSHA, ANSI, and

ASME.

The operator is also responsible for understanding the environ-

ment the forklift is being operated in. Knowing how to operate the

forklift within their working environment is very important to overall

forklift safety.

Operate your forklift safely; careful driving is your responsibility.

Know your forklift’s capabilities and limits. Follow all instructions in

this manual.

IMPORTANT INFORMATION ON THE FILTRATION

OF YOUR PB SERIES

Your PB Series unit is equipped with a “suction boost” filter. This filter

provides superior protection to the drive circuit. It is equipped with a

dash mounted notification light that indicates if the filter needs changed.

This light is additional information for the operator and is not a

substitute for filter changes during PM’s.

This light will normally illuminate* under three circumstances.

1) During cold weather operation, the light may illuminate until

the hydraulic oil warms. This generally takes 1 to 3 minutes of

operation.

2) During high-speed multi-function operation, the light may

illuminate temporarily.

3) If the light remains on at any other time the filter should be

changed.

*An illuminated light does not mean the filter is by-passing but indicates

contaminates in the hydraulic system.

A “break-in” filter change is recommended in the first 5-10 hours of

operation.
